The file name, path, Local and Global prevalence are indicators that can provide an initial analysis of the file without relying on external sources or tools. The file name can indicate the purpose or origin of the file, such as if it is a legitimate application or a malicious payload. The file path can indicate where the file was located or executed from, such as if it was in a temporary or system directory. The Local and Globalprevalence can indicate how common or rare the file is within the environment or across all Falcon customers, which can help assess the risk or impact of the file.
